Oxford, 1887. Even as Victoria celebrates the fiftieth year of her reign, a stone"s throw from the calm cloisters and college spires lies Jericho, a maze of seedy streets and ill-lit taverns, haunted by drunkards, thieves and the lowest sort of brazen female as ever lifted her petticoats. When Stephen Chapman, a brilliant young medical student, is persuaded to volunteer at a shelter devoted to reforming the fallen women of Oxford, his closest friend Edward feels a strange sense of dread. But even Edward - who already knows the devastating effect of falling in love with the wrong woman - cannot foresee the macabre and violent events that will unfold around them, or stop Diana, the woman who seems destined to drive them apart.
